Hi
I would like to add a small icon to the location pointed by the red crosses for multicolumn, and be able to control its size.
Hi @Pietrach for such purpose you need to edit mulicolumn section liquid file. You need to add new settings and code for rendering these settings.
here’s a reference for that https://shopify.dev/docs/storefronts/themes/architecture/settings/input-settings
Hi @Pietrach
Yes, you should develop a section based on the Multicolumn. And it is necessary to work in Liquid code.
If you are not familiar with codebase, I can help you.
Regards,
Vinh
Thank you for your response. Unfortunately I cannot code 
Is this something you could help with?
